Manufacturing: The Foundation of the USA

We are committed to keeping manufacturing the backbone of the American economy. By supporting American manufacturing, we contribute to job creation, economic growth and the overall strength of our country. Partnering with a US-based manufacturer like E-S Plastics offers numerous benefits, including shorter lead times, better communication and the assurance of adhering to rigorous quality and safety standards. We serve several customers that have tooling dual sourced.

Benefits of Two Facility Locations

Our two facilities in Wisconsin are strategically located to maximize efficiency and capacity. The benefits of having multiple locations include:

  • Increased Capacity: With two facilities, we can handle larger volumes and more complex projects, ensuring we meet your production needs.

  • Operational Flexibility: Multiple locations provide the flexibility to distribute workloads, optimize production schedules and mitigate risks associated with single-site operations.

  • Enhanced Reliability/Natural Disaster Recovery: In the event of unforeseen disruptions, having two facilities ensures continuity of service, minimizing downtime and maintaining consistent delivery.
